Fearne, Katherine, Helen and Sophie - celebrity bumps on show

Fearne Cotton in yellow and red

In particular, it’s been a very busy week for Fearne Cotton. She’s just about to embark on her maternity leave and went out with a musical bang.

The DJ spent the weekend draping her bump in an oversized shirt dress and yellow smock top while presenting the Big Weekend in Norwich. It's her final duty for Radio 1 before she hangs up her mic at the radio station for good - coinciding with her taking time off before the arrival of her second baby with Jesse Wood. But she's not planning to disappear out of public view for long.

Speaking to The Mirror newspaper she says, “People do want to know what I'm doing next and this is genuinely the first time that I've not known. It's quite liberating. Just because I'm stopping radio doesn't mean that I'm going to be a stay at home mum."

She then quickly added(!), "Not that there's anything wrong with that. But for me, I love my job, so I couldn't ever imagine just being a mum. I need to work and I love to work. We'll see what happens next but I genuinely don't know."

Katherine Jenkins - can you spot her bump yet?

It was business as usual for mum-to-be Katherine Jenkins who was performing at the 26th Anniversary Broadcast Of The National Memorial Day Concert in Washington DC.

The singer only showed a mere hint of a bump in a beautiful floor-length midnight blue gown with a cinched in waist and lace bodice, that she had chosen to wear for her performance.

Earlier in the day she tweeted her excitement about performing at the concert but also showed her delight at being pregnant with her #BumpOnTour hash tag.

It was only last month that Katherine shared the news that she was expecting a baby with her new husband Andrew Levitas by posting a picture of a pair of pink ballet slippers resting on top of the couple's black-and-white wedding photograph.

Sophie Hunter with her Cumberbump

Benedict Cumberbatch and his wife Sophie Hunter have been spotted out and about in Primrose Hill.

The couple, who got married earlier this year on Valentine’s Day were photographed doing a bit of shopping. Sophie's due date is fast approaching but we're pretty sure those bags in Benedict's hand don't contain any baby items.
